WIn7 SP1 x64 - White Flashing Line After Install

Posted on 2011-03-16

Last Modified: 2012-05-11

I upgraded to Win 7 SP1 and when my computer restarted I ended up with a white blinking cursor and windows doesn't even attempt to start.

I tried removing all of the periferals such as the video card and still get the white blinking line.

What can I do?

Known issue going around with SP1.

01. Reboot your computer while it's starting up.
02. When your computer starts up again, choose the option "Launch Startup Repair"
 --> PIC: http://notebooks.com/wp-content/uploads/2011/01/Recov-1.jpg
03. When the Startup repair starts, click cancel.
04. After you click cancel it will show a box. Click "Don't Send"
 --> PIC: http://i52.tinypic.com/xgjriw.png
05. Click the link "View advanced options for recovery and support"
06. In the new window click Command Prompt at the bottom.
 --> PIC: http://i51.tinypic.com/50imu8.png
07. In Command Prompt type this and press enter: notepad.exe
08. Notepad will open. In notepad go to File-->Open.
09. Change the type of files notepad views from .txt to All Files (see pic)
 --> PIC: http://i51.tinypic.com/35nd74z.png
10. Now in Notepad, go to C:\Windows\winsxs\ (or whichever drive Windows is installed on)
11. In that folder, find pending.xml and make a copy of it
12. Now open the original pending.xml (it will load really slow because the file is huge)
13. Press CNTRL+F and search for the following exactly: 0000000000000000.cdf-ms
14. Delete the following text (yours will be a little different):
<DeleteFile path="\SystemRoot\WinSxS\FileMaps\_0000000000000000.cdf-ms"/>
<MoveFile source="\SystemRoot\WinSxS\Temp\PendingRenames\e56db1db48d4cb0199440000b01de419._0000000000000000.cdf-ms" destination="\SystemRoot\WinSxS\FileMaps\_0000000000000000.cdf-ms"/>
--> PIC: http://i54.tinypic.com/adzpzp.png
Your PC might not have all 3 sections of code (<Checkpoint>, <DeleteFile>, <MoveFile>). Just make sure you delete section "Checkpoint" and whatever other sections have "000000000000000.cdf-ms". They will be right next to eachother.
15. Save the file, close notepad, close command prompt, restart your computer.
Once your computer starts up, do a normal startup (it may stall for 5-10 minutes at the "starting windows" screen, but leave it going) and the Service Pack will install some more stuff and restart a few times and then everything should be working! For some people, it reverts everything and cancels the service pack installation. For other people, the service pack installation completes. Either result is fine.

Hi operationnos

Your solution would be the prefered rout. However, I never get past the boot sequence.

When I carry out the following

01. Reboot your computer while it's starting up.

I get the acer splash screen, bootup info and white blinking light.

I think your screenshots show a computer that has started the windows boot-up process.

Am I doing something wrong?

Hi Cpanel

That will mean a lot of work for me. I will need to reinstall lots of other software too.

I'd like to explore any alternatives first.

Rather than reinstalling, it would probably be a better idea to attempt a repair installation from your installation media.  Do you have the original Windows 7 installation disk available?  

Cpanel:  please provide more detail when providing a solution.  "Reinstall Windows" is not a solution to the problem.

Hi Operationnos

It's an acer desktop and all I have is a rebuild disk that offers me the choice of re setting to factory install whilst saving my data or wiping and resetting.

I've got to nip out for an hour or so but I'll re explore the options when I get back.

Thanks for the help. Speak soon.

What version of Windows 7 is your system?  Home, Pro, Ulimate, etc?

Any Windows 7 install media of the same version should allow you to do the repair install, thus leaving your applications and data intact.  Do you have any available resources to get a normal install disc?

He's going somewhere for an hour and won't be near the system during that time.  Troubleshooting can continue when he returns.

Cpanel, you give the same answer to everyone and it's almost always incorrect.  At this site we try and solve issues without destroying all of the user's data and programs.  Please consider this before you tell people to reinstall Windows.

Hi Operationnos

I appreciate your structured and supportive approach. Unfortunately I don't have access to an installation disk so for speed I've opted to use the acer recovery method which backs-up the user data in a new partition and restores the system to factory settings.

Kind Regards

Hi Operationnos,

A quick update. SP1 Auto Update trashed my computer as you know.

However, I downloaded the SP1 DVD image and success!

I wish I'd done that at 11am this morning.

Many Thanks
